Rainbows. Signs.

Relationships in creation. God, Noah, creatures. NB animal sacrifice - Noah has just taken

of every clean animal and of every clean bird, and offered burnt-offerings on the altar

which appears to be why God has decided not to send another flood. First mention of animal sacrifice in Genesis, and thus in the Bible, but there's no account establishing it. (It takes until Leviticus 11 before there's any explanation of which animals are clean or unclean.) What is going on here? What are the relationships implied in the covenant? What is God's motivation in sending the flood and not sending another?

Relationships again. Peter: Jesus is the Lord and the one anointed, and you crucified him. Everyone: what should we do? Peter: repent and receive the Spirit.

The Spirit more or less is a relationship. Not a very personal Person of the Trinity.

Even more relationships. Neighbours, enemies, brothers, sisters, the good, the evil, tax-collectors, gentiles. And rain.

What does 'perfect' mean?
